So my laptop will no longer connect to the Internet via Wifi. Two other laptops and a desktop and my iPad can connect but not my main laptop. What can I check to see where the break down is. It's an HP running Windows 8(which is a piece of shit OS) and google chrome. Google chrome on all computers and this is the only one I am having this issue with. And it started suddenly a couple of days ago.

It says I'm connected and I verified the code buts that's about as far as my skills go...
